ETS SM8-RC Remote Controllable Microphone Mixer/Switcher/Amplifier W/ Level Controls
The ETS SM8-RC is an RS232 controllable microphone switcher / mixer / amplifier for remote monitored audio surveillance systems. The SM8-RC connects to video/audio transmission equipment (with an available RS232 port) that uses telephone, internet, or LAN mediums.
The SM8-RC fills a need when the transmission equipment lacks a sufficient number of microphone audio inputs and switching / mixing capabilities. Programming is required by the remote equipment manufacturer to control the SM8-RC via RS232.
The SM8-RC Powers up to eight SM1 pre-amplified microphones and outputs a line level audio signal. It also can be expanded to 32 microphone zones by looping connections from an SM8-RC to up to 3 additional SM8-RCs.
Finally simple ASCII commands control the SM8-RCs via RS232.
